Kerber, Ostapenko set up Wimbledon semi

Latvian history-maker Jelena Ostapenko is within sight of a second grand slam crown in 13 months after surging into the Wimbledon semi-finals for the first time.

The 2017 French Open champion ended Dominika Cibulkova's inspired run with a 7-5 6-4 quarter-final triumph on Tuesday.

The 12th seed was the first woman through to the last four and will play resurgent former world No.1 Angelique Kerber for a spot in Saturday's title decider after the German followed up with a 6-3 7-5 win over Russian 14th seed Daria Kasatkina.

Rebounding from her shock first-round elimination in her Roland Garros title defence, Ostapenko has marched through the Wimbledon draw without dropping a set.

"I was down in the first set but I kept fighting. I'm fighting to the end and it helps me, gives me more confidence," said the 21-year-old and youngest player left in the draw.

"It was a very tough match but I was just trying to enjoy it. I'm happy to be in the second week, quarter-finals and now the semi-finals."

Runner-up at The All England Club two years ago, as well as winning the 2016 Australian Open and US Open crowns, Kerber looks on a mission to atone for a disappointing season in the slams in 2017.

The German struck 33 winners to Kasatkina's 16 to move through in one hour, 29 minutes.

Kerber and Ostapenko have never clashed before but the showdown ensures a grand slam champion will make the final.

"I don't care who I am playing against. We are here in the semis and they are all tough opponents and you have to play at your best," Kerber said.

With no top-10 seeds making the quarter-finals for the first time in Wimbledon history, 11th-seeded Kerber is the highest-ranked player left in the hunt for the Venus Rosewater Dish.

Ominously, though, seven-times champion Serena Williams will try to make the last four later on Tuesday when she contests her 13th semi-final at The All England Club in just her fourth tournament back after taking more than a year off to have her daughter Olympia.
